Hey Michael. Thanks for your comprehensive reply.

We both know that iPhone's 8MP sensor is limited to 3264x2448 and that we are both upscaling. But in your review on the App Store and your comments here, the only point that you inaccurately stressed was that ProCam renders videos at 3264x1836 while Vizzywig produces 4K resolution (3840x2160) natively. You mention this point over and over in your comments. This again suggests that you are misleading users.

With regards to our in-app purchase's title, your app came out as Vizzywig 4K and was renamed 8xHD, which in exactly the same as 4K Ultra HD.

First, you argued that with a $160 ad on lens, your app achieves 4K resolution natively. Apart from the cost, nowhere in your description do you mention that this is a requirement to achieve 4K. Then you started de-emphasizing resolution and focusing on JPEG compression, making it sound like rocket science. It's one line of code!

We deliberately reduced our bitrate after reading reviews about Vizzywig and user comments. No one wants a $50 app that can't shoot more than 5 min of video on a 64GB model!

Going back and forth is a bit pointless as we both feel very strongly about our apps as it should be.

Again, we would appreciate it if you would remove your review from the App Store. We make it our policy not to rate / review competing apps whether we like them or are unimpressed with them.

We wish you all the best going forward.

Michael, with all do respect, that's a very weak argument. Vizzywig 8xHD without the $160 anamorphic lens add on produces the same quality videos as ProCam. The only difference is that we don't try to conceal our methodology.

About JPEG compression, it's very easy to use a higher JPEG quality and increase bitrates. However, for us, the most important goal was to find the right balance between video quality and practicality. After all, we are talking about shooting 4K videos on a smart phone with limited storage.

By the way, we'd appreciate it if you could remove your 1 star review on the App Store. It's very unprofessional. We have refrained from doing the same.

Thanks.

Thanks Tony. Glad you're enjoying ProCam.

It's very easy for us to increase bitrates and we are considering adding a higher bitrate option in the next update. It is not rocket science, as Michael makes it out to be!

In-terms of shutter speed, ProCam offers 3 standard frame rate options and a user defined one.

Vizzywig's claims of encoding in native 4K resolution are false. The iPhone's 8MP sensor produces 3264x2448 resolution images. Vizzywig is upscaling each image from 3264x1836 to 3840x2160 before encoding the video, while we encode the video at 3264x1836 and then upscale to 3840x2160. Our method produces the same results but much more efficiently.

Now about the editing capabilities, we don't think they are worth an additional $45!

Hey Michael. Nice job on talking down the competition. Let me introduce my self. I'm the lead developer on ProCam 2. First, let's be clear about one thing. The iPhone's 8MP sensor produces 3264x2448 resolution images. This means that your claims of native 4K resolution are a blatant lie. What your doing is upscaling each image from 3264x1836 to 3840x2160 before encoding the video, while we encode the video at 3264x1836 and then upscale to 3840x2160.
